通过分析三明森林城市建设中存在的可用地面积少、森林布局不合理、缺乏系统性,森林结构简单、树种选择及配置不合理、缺乏植物多样性,生物多样性受到严重破坏,苗圃发展与森林发展相脱节、苗木自给率低,森林城市建设缺乏有效的监管与养护机制等问题,针对性地提出了发挥现有生态公益林的综合性生态功能,城市规划建设与宜居城市建设相结合,拓宽和续建现有生物防火林带,沙溪河城区两岸建设竹林生物林带,实施主干道两旁增绿添荫工程和调整树种、林种结构,保护和管理好区域内的自然保护区和森林公园等对策,以建设森林城市体系,构建宜居生态三明。 相似文献

基于高密度城市群城市森林建设的特殊性与复杂性,提出了高密度城市群城市森林建设不仅要遵循生态功能优先原则、维持生物多样性原则、因地制宜原则等城市森林建设的一般原则外,还应遵循系统性建设、均衡性发展、复合性管理三大特殊原则。根据以上建设原则,通过以长株潭城市群城市森林建设现状为例进行分析,进而对促进高密度城市群森林建设的可持续发展提出了对策建议。 相似文献

城市森林健康与监测评价研究进展 总被引：1，自引：0，他引：1
城市森林作为城市生态系统的重要组成部分,具有重要的生态功能和社会功能。城市森林健康是保证其各项功能发挥的前提。城市森林的健康状况将直接影响城市的可持续发展。城市森林健康是一个综合概念,要求不仅满足自身生态系统的健康,还应满足人类社会的经济、文化等各方面的需求。文中分析了影响城市森林健康的因素,城市环境的特殊性和人类活动是影响城市森林健康的主要原因。介绍了我国城市森林健康监测评价指标的筛选和评价方法的选择,认为其还处于实验和摸索阶段,尚未形成一套成熟的体系。城市森林结构的破碎化等特征严重影响了城市森林的自我修复能力。为保证城市森林的健康生长,众多学者从宏观尺度和个体尺度上研究城市森林健康的维护措施。文中指出城市森林健康及其监测评价研究存在的不足之处,在总结前人研究成果的基础上提出几点建议。 相似文献

Jerome K. Vanclay 《Small-Scale Forestry》2007,6(2):177-188
An on-line survey during August–September 2006 examined community attitudes toward private native forestry. Views expressed
by the 156 respondents confirmed prior hypotheses that attitudes would correlate with associations (e.g. professionals in
favour of incentives, farmers in favour of freedom to manage, conservationists in favour of regulations), and with interest
(biodiversity enthusiasts in favour of regulations, producers in favour of incentives), but refuted the prior hypotheses that
urban dwellers would be more likely to favour regulations. Respondents appear to reflect different constituencies with divergent
views without a shared understanding of the condition and dynamics of private native forests in NSW. This indicates the need
for more extension and public education, particularly since forests continue to be an election issue. The survey did not gauge
support for private native forestry, but helps to untangle the views from the constituencies promoting them. Regulatory approaches
received most support from respondents affiliated with an environmental group, with a national concern for biodiversity, who
fear that private native forests are in poor condition and will degrade further. Advocates for more landholder freedom tend
to be landholders who believe that private native forests are in better condition than comparable State Forests, and who are
optimistic about the future for private native forests. Advocates for incentives tend to be urban dwellers with a production
focus and professional affiliation. 相似文献

Abstract Tropical forests are very rich in biological diversity and form an important economic and ecological resource. This biodiversity is of great value for communities living in or near these forests as a ready source of subsistence and cash income, and for the world at large as a source of tropical timber and non-timber products and a repository of genetic and chemical information. However, this biological complexity is diminishing rapidly. We analyze the main human (anthropogenic) actions causing loss of tropical forest biodiversity along with the strategies of management for forest biodiversity. Not only is the biophysical component important in management for biodiversity, but the active participation and support of local people, national governments, and the international community as a whole are essential to effective and sustainable development of tropical forests. This development strategy ensures that socioeconomic and environmental benefits are provided for present and future generations. 相似文献
